This is an MK6-style nozzle. It is made of 360 brass and features a TwinClad XT coating. TwinClad XT is a nickel composite coating designed for very low friction. It offers one of the lowest coefficients of friction, outperforming nickel with PTFE co-deposition. This coating is also very hard and abrasion-resistant. If you work with abrasive carbon fiber, stainless steel, wood-filled, or other metal-filled filaments, this coating reliably protects the nozzle from premature wear.
